My Vinvention relates to improvementsV in door knob construction and mounting means wherein a tubular sleeve is mounted `axially through aV knob -body `and provided with 5 means forrigidly securing the 'sleeve in assembled relation to the knobgtozprevent relativel rotation thereof and arranged to be keyed to f aknob spindle in a desired vaxial adjustment relative thereto.

. l0 The primary: objectof myy invention is to provide an-improved doorknobconstruction. Another Objectis to provide an .improved knob construction-which will facilit ufacture and installation. 1

A further object is to provide an improved knob construction wherein the parts' areneffectually secured in assembled relation an held against relative rotation.

Another object: is .tov provide improved ate man-- means for assembling aknob spindle andv knob whereby the spindle vmay be adjusted axially to a desired position relativeL toy the knob and keyed against rotation relative'toY theknob.V Y Al still further'object is to provide' an improved device of the character" described embodying improved features of construction and arrangement',V aording increased .utility and increased eiciency. y

I accomplish these and other objects by means of the improveddevice disclosed in the drawings forming a part of the present application wherein like characters of reference are used to designate similar parts throughout theV specication and drawings, and vin whichj e Fig. 1 is a longitudinal mid-section of-my improved door knob construction; Y

Fig. 2 is an elevation ofthe outer end of the knob, the end closingmeans being removed; Y j

Fig. 3 is an elevation of the inner endof the knob asshown in Fig. 1; l j

Fig. l` isV an yenlarged endelevation, Apartly in section, of the sleeve and spindleassembly; and Y Fig. 5 is aV broken sectional view taken upon vthe line 5-5 of Fig. 4 in the direction sleeve wall adjacent the outer endof the indicated, Athe key being omitted.

Referring to theV drawings, the numeral1 1930. semi No. 469,061;

is used to designate inV general the body of al door knob; having an openingr2 extending axially therethrough and having recesses 3 and t'formedin the outer and innerk ends of the knob' respectively around the open.y ends of the opening 2. The knob body 1 may be of any of any suitable material.

. A sleeve designated in general by the numeral 6 is mounted in the opening 2. Lugs 7 are formed upon the outer end of the sleeve 6 to seat within the recessesl 8formed in the back of the recess 3 ofthe knob body to secure the sleeveagainst'rotation relative to the knob. v'lhe opposite end of the sleeve 6 eX- tends outwardly from the knob and'isprovided with a collar 9 seatingwithin the recess suitable design and `may be formedY l 4 of the knob body. lA bushing 11 is mounted in the'end ofthe sleeve 6 adjacent the collar 9. The sleeve 611s preferably split and the bushing 11. is arranged to form a tight press ,-it within the end of the sleeve whereby said bushingoperates to expand the sleeve within the'collar and thereby clamp the sleeve in assembled relation to theknob.

The bushing 111 is provided lwith an Aaxial opening threaded as at 12 to engage threads j 13 formed upon the end of aknob spindle 14.

whereby the spindle is locked against rotation relative tothe bushing. Y

The bushing 11 lhas a plurality of .notches 18 formed in the periphery thereof atithe outer endV of the bushing.v Indents 19 are. pressed into the end' ofv the sleeve 6 to engage the notches 18 when the bushing 11v is assembled into the sleeve, thereby eil'ectually securing the` bushing within the end of the sleeve and preventing rotation of thebushing relativ-e to.v the sleeve. y

Detents 21 are pressed inwardly from the to close the outer end of the sleeve 6. The member 22 may be of any desired nature, such as the simple end cap indicated in Fig. 1 ot the drawings, or the face plate ot lock mechanism mounted within the sleeve 6.

In assembling; the sleeve o is inserted through the outer end of the knob and the collar 9 moved onto the inner end of the sleeve to seat in the recess 4. The bushing 11 is then pressed into the inner end of the sleeve to expand said sleeve within the collar and thereby secure the sleeve against longitudinal movement within the knob. he indents 19 are then pressed into the end ot the sleeve tol engage the notches 18 and thereby prevent rotation of the bushing within the sleeve and hold the several elements in Aassembled relation.

The spindle 14 is then screwed into the bushing 11, the spindle being advanced` along the threads 12 to a desired axially adjusted position. The key 17 is then inserted through the open outer end of the sleeve G and into the key-way 16, the spindle 14; being turned to present a iiat key engaging face to the inner face of the key whereby the spindle is ei'tectually locked against rotation within the bushing.

The hollow sleeve 6 provid-es a. chamber within the knob Vto receive locking mechanism of any suitable nature. As such locking mechanism `forms no part of the present invention, this mechanism has been omitted from the drawings. l/Vhere the provision of locking mechanism is not required, the outer end of the sleeve 6 is covered by means ot an end cap 22 seating against the outer end .of the knob and provided with an inwardly lextending ange 23 having recesses 24 engaged by the spring detents 21 whereby the cap 22 is effectually secured upon the knob. The cap 22 may be pri-ed free from the sleeve to give access to the interior of the` sleeve if desired.

Should the knob be broken or Jfor any reason it be desired to replace the knob body7 the key 17 may be withdrawn and the knobassembly removed from the spindle. The bushing may then be pressed outwardly from the sleeve and the several parts assembled upon a desired knob body as above described.

The speciiic details of construction and arrangement as herein illustrated and described represent what l now believe to be the preferred embodiment of my invention. However, I do not wish to be restricted to the precise details illustrated, but desire to avail myself of such modiiications hereof as may -fall within the scope of the appended claims.
